Forty-nine-year-old Saumya Sood underwent two hip replacements in her mid-30s but continues to run a cafe in Goa and engage in rock-climbing. A Lancet study indicates that 92% of modern hip implants are likely to last at least 25 years. This advancement stems from improvements in materials and manufacturing techniques.
Saumya Sood, now 49, suffered avascular necrosis (AVN) in both femurs following a road accident in Delhi, where bone tissue died due to lack of blood supply. The pain intensified over time, and by the time her daughter was born, she struggled to walk or rise from bed as her joints locked. In 2009, she had her first hip replacement, followed by the second in 2010, both performed by Dr. Rajeev Joshi at Sancheti Hospital in Pune.
Two decades later, Sood runs a cafe in Goa, rock-climbs, and parasails. Dr. Joshi notes, “The longevity of hip replacements has improved significantly in recent years. This progress is directly linked to advances in manufacturing techniques and the development of more durable bearing surfaces used in hip joint replacements.”
A systematic review and meta-analysis published in The Lancet used data from eight national joint registries covering nearly 1.9 million hip replacements and clinical studies with over 5,000 patients. Advanced modeling concluded that 92% of modern implants are likely to last at least 25 years, up from about 58% for older technologies. Improvements include highly cross-linked polyethylene, ceramics, and titanium, which reduce wear and enhance bone integration. Veronica Pentland from Queen’s School of Medicine in Kingston, Ontario, Canada, a joint author, states that further modeling shows 91% could function for at least 30 years.
While the findings reassure at a population level, individual outcomes depend on factors like age, overall health, bone quality, and surgical technique. Dr. Joshi emphasizes that bone is living tissue that strengthens with exercise. “Implants do not make us walk; we make the implant walk. Muscle strength and regular movement are key,” he says. Sood has focused on bone health, becoming physically stronger than ever.
